Go's appearance could have been inspired by [http://streetfighter.wikia.com/wiki/File:SagatArt4.jpg an illustration] showing [[Sagat]] holding a man similar to Dan by the head. The man also appears in one of Sagat's intro animations in the ''[[Street Fighter Alpha series|Street Fighter Alpha]]'' series. The character in question has been speculated to be Go, but this has never been confirmed nor denied.
In ''[[Pocket Fighter]]'', Go remains somewhat similar in appearance to Dan, though he sports a green gi and a halo over his head. He also has more of a [[wikipedia:Tengu|tengu]]-like appearance, with red skin, a wide double chin, and a long nose. Much like Dan, this design is a parody of [[w:c:snk:SNK|SNK]] character [[w:c:snk:Mr. Karate|Mr. Karate]] and his trademark ''tengu'' mask. Mr. Karate is the father of [[w:c:snk:Ryo Sakazaki|Ryo Sakazaki]], whom Dan is designed to parody.
In the UDON comics, his facial structure is slightly based on his ''Pocket Fighter'' appearance, with a wide cleft chin and a slightly longer nose. His hairstyle is slightly similar to Dan's, but short without a ponytail.
